TOOL-HANDLE HOLDER.

aoaacc Specification of Letters Patent. Patented July 23, 1912,Application filed April 23, 1912. Serial No. 692,743.

of G rand Forks, in the county of Grand 1* orks and State of NorthDakota, have invented a new and Improved Tool-Handle Holder, of whichthe following is a full,

clear, and exact description.

This invention relates to tools or imple-.

ments, such as garden rakes, hoes, forks, chisels, screwdrivers and thelike, and pertains especially to devices whereby asingle holder may beused successively for attaching a single xhandle tovarious tools ofsimilar ordifi'erentcharacter, or for the purpose of renewal of a brokenor defective handle in a certain tool or set of tools.

The invention consists essentially in the construction and combinationof parts herefss inafter fully described and claimed and illustrated inthe accompanying drawings, in which- Figure 1 is a side view of a toolhandle holder shown in assembled position; Fig. 2 is a substantiallylongitudinal vertical section of the same, on the line 2-2 of Fig.3;Fig. 3 is a substantially horizontal sect-ion on the line 33 of Fig. 1,and Fig. 1 is a view similar to Fig. 3 but indicating the partspartially assembled; v I I Throughout the following detail descriptionand on the several figures of the drawings similar parts are indicatedby like reference characters.

At 10 is indicated a socket member ofany form or construction suited toany particular application of the device, made preferably of metal, andhaving the socket 11 for the reception of a handle 12. This socketmaybeprovided if desired with an extension 11 of reduced size,'into which isfitted the lug or extension 12 of a handle 12,

whereby the rigidity and stability of the handle connection areincreased. Said handle is removably though rigidly secured in the socketby one or more removable means, such as screws 13, as shown.

The socket member 10, at the end opposite the handle, is cylindrical inform at 14, the inner end of such cylinder terminating in a shoulder 15,and that port-ion of the member 10 between said shoulder and the mainbody thereof is formed frusto-conical at 16. Said cylindrical end isprovided with a transverse key seat 17 and with a central longitudinalthreaded bore 18, which may extend, for convenience of manufacture, all

the way into the aforesaid socket extension 11. The other principalmember of this holder consists of a substantially cylindrical ferrule19, having a rotatable and sliding fit upon the aforesaid cylindricalend 14 of the socket member 10and having its inner end 20 of hollowconical form, to abut against the surface 16 of the socket member. Theouter end of the ferrule is formed with a rectangular bore 21 andadjacent shoulders 22. A pair of oppositely-arranged openings or slots23 is provided in the ferrule, so as to register with said key seat 17.

The tool 24, of whatever description, is presumed to be provided with ashank 25 to fit the bore 21 and with shoulders 26 to abut against theferrule shoulders 22, whereby the tool will be snugly seated in theferrule and will rotate therewith around and along the cylinder let. Theextreme end of the shank is threaded at 27, for cooperation with thethreaded bore 18, whereby the tool and ferrule are caused to bind snuglyagainst the cylinder 14 and conical surface 16 of the socket member 10.Accidental or unintended rotation or displacement of the tool andferrule are prevented by any suitable positive locking means, such as aremovable cotter 28 passing through the shank and registering openings17 and 23.

The relative sizes and proportions of the holder may be modified withincertain limits without departing from the spirit of the invention, andthe form illustrated is to be understood as being merely suggestive ofmany specific forms which maybe produced within the scope of theinvention claimed.

Amongthe several advantages of this device considered as an improvementover others previously proposed for similar purposes, is the fact thatthe constructionprov'idcs an easily detachable and interchangeableconnection, having a neat appearance, and through its simpleconstruction itis feasible to form the socket member with its ends at anangle to each other, as is customary in certain classes of implements,and yet not interfere in any way with the free manipulation of thehandle or the tool inde-' her having means at one end to detachablysecure a handle and having its other end of cylindrical formation with athreaded longitudinal bore to receive the threaded shank of an suitabletool, a ferrule rotatable aroun and slidable along said cylindrical end,and detachable positlve means to lock the ferrule from such rotation.

. 2. The combination of a socket member, a handle removably secured inone end thereof, the other end of such member being provided with athreaded bore and a trans verse key seat, a ferrule snugly fitted uponthe latter mentioned end and provided with a rectangular bore, a toolshank fitted in said rectangular bore and having its extreme endthreaded into said threaded bore independent of said handle, and meansin said key seat positively preventing rotation and displacement of saidferrule and tool, substantially as set forth.

3. The combination of a holder member having a cylindrical end and anadjacent frusto-conic'al surface, aferrule having rotatable and slidablefit upon said cylindrical end and having one of its ends of hollowconical form to cooperate with said frustoconical surface, a tool shankfitted into and tions snugly together,

against the other end of said ferrule, and removable means positivelypreventing relative movement between the ferrule and the holder member.

4. The combination of a socket member having one end of cylindrical formwith an adjacent frusto-conical surface, said end having a centralthreaded bore and a transverse kev seat, a ferrule having a rotary andsliding t upon said cylindrical end and having a hollow conical endabutting against said frusto-conical surface, the other end of theferrule being formed with a rectangular bore with adjacent shoulders, atool shank fitted into said ferrule bore and against said shoulders andalso screwed into said threaded bore, holding said conical porand meansin said key seat positively preventing relative movement between theferrule and the socket member.

In testimony whereof I have name to this specification in the twosubscribing witnesses.
